The Natural Laws of Memory
Concentrated attention at the time when you wish to store the mind is the first step in memorizing—and the most important one by far. You forgot the fourth of the list of articles your wife asked you to bring home chiefly because you allowed your attention to waver for an instant when she was telling you. Attention may not be concentrated attention. When a siphon is charged with gas it is sufficiently filled with the carbonic acid vapor to make its influence felt; a mind charged with an idea is charged to a degree sufficient to hold it. Too much charging will make the siphon burst; too much attention to trifles leads to insanity. Adequate attention, then, is the fundamental secret of remembering.
Generally we do not give a fact adequate attention when it does not seem important. Almost everyone has seen how the seeds in an apple point, and has memorized the date of Washington's death. Most of us have—perhaps wisely—forgotten both. The little nick in the bark of a tree is healed over and obliterated in a season, but the gashes in the trees around Gettysburg are still apparent after fifty years. Impressions that are gathered lightly are soon obliterated. Only deep impressions can be recalled at will. Henry Ward Beecher said: "One intense hour will do more than dreamy years." To memorize ideas and words, concentrate on them until they are fixed firmly and deeply in your mind and accord to them their true importance. Listen with the mind and you will remember.
How shall you concentrate? How would you increase the fighting-effectiveness of a man-of-war? One vital way would be to increase the size and number of its guns. To strengthen your memory, increase both the number and the force of your mental impressions by attending to them intensely. Loose, skimming reading, and drifting habits of reading destroy memory power. However, as most books and newspapers do not warrant any other kind of attention, it will not do altogether to condemn this method of reading; but avoid it when you are trying to memorize.
Environment has a strong influence upon concentration, until you have learned to be alone in a crowd and undisturbed by clamor. When you set out to memorize a fact or a speech, you may find the task easier away from all sounds and moving objects. All impressions foreign to the one you desire to fix in your mind must be eliminated.
The next great step in memorizing is to pick out the essentials of the subject, arrange them in order, and dwell upon them intently. Think clearly of each essential, one after the other. Thinking a thing—not allowing the mind to wander to non-essentials—is really memorizing.
Association of ideas is universally recognized as an essential in memory work; indeed, whole systems of memory training have been founded on this principle.
Many speakers memorize only the outlines of their addresses, filling in the words at the moment of speaking. Some have found it helpful to remember an outline by associating the different points with objects in the room. Speaking on "Peace," you may wish to dwell on the cost the cruelty, and the failure of war, and so lead to the justice of arbitration. Before going on the platform if you will associate four divisions of your outline with four objects in the room, this association may help you to recall them. You may be prone to forget your third point, but you remember that once when you were speaking the electric lights failed, so arbitrarily the electric light globe will help you to remember "failure." Such associations, being unique, tend to stick in the mind. While recently speaking on the six kinds of imagination the present writer formed them into an acrostic—visual, auditory, motor, gustatory, olfactory, and tactile, furnished the nonsense word vamgot, but the six points were easily remembered.
In the same way that children are taught to remember the spelling of teasing words—separate comes from separ—and as an automobile driver remembers that two C's and then two H's lead him into Castor Road, Cottman Street, Haynes Street and Henry Street, so important points in your address may be fixed in mind by arbitrary symbols invented by yourself. The very work of devising the scheme is a memory action. The psychological process is simple: it is one of noting intently the steps by which a fact, or a truth, or even a word, has come to you. Take advantage of this tendency of the mind to remember by association.
Repetition is a powerful aid to memory. Thurlow Weed, the journalist and political leader, was troubled because he so easily forgot the names of persons he met from day to day. He corrected the weakness, relates Professor William James, by forming the habit of attending carefully to names he had heard during the day and then repeating them to his wife every evening. Doubtless Mrs. Weed was heroically longsuffering, but the device worked admirably.
